Question

Which of the following describes a key aspect of a nuclear power generation system?

a. nuclear fission directly produces electricity
b. nuclear fission splits a large atom into smaller ones
c. nuclear fission joins two atoms into a larger one
d. nuclear fission occurs in a powerhouse

Answer 1

Nuclear power generation involves nuclear fission, where a large nucleus is split into smaller ones, releasing energy that is used to produce electricity by turning a turbine.

Step-by-step explanation:

The key aspect of a nuclear power generation system described by one of the options is (b) nuclear fission splits a large atom into smaller ones.

This process, called nuclear fission, involves the splitting of a large atomic nucleus such as uranium-235 (U-235) into smaller nuclei, releasing a significant amount of energy in the form of heat and radiation.

This energy is then used to produce hot, high-pressure steam that turns a turbine, and as the turbine turns, electricity is generated.
